Title: Method for effecting sanding
Inventor: STERNAL LAMBERT STANLEY
IPC: B24B21/12
Filed: 1971-03-18
Abstract: 1,272,045. Grinding. TIMESAVERS SANDERS Inc. 18 March, 1971 [11 Sept., 1970], No. 7206/71. Addition to 1,249,785. Heading B3D. A method of sanding a flat wooden surface of a workpiece B the grain of which runs lengthwise thereof, comprises training an endless abrasive belt 9<SP>1</SP> over a plurality of roles, one of which is a contact drum 11<SP>1</SP>, feeding the workpiece along a straight path with the abrasive belt pressed by the contact drum against the surface to be sanded along a narrow work performing zone parallel to the axis of the drum, and so relating the axis of the drum to the path of the workpiece that the narrow zone forms an angle of greater than 60 degrees and less than 75 degrees to the path of the workpiece. In apparatus for carrying out the method, workpieces B are fed by a belt conveyer 15 between mirror image upper and lower units 6, 7, each having an abrasive belt 9<SP>1</SP> trained about a driven contact roller 11<SP>1</SP> and an idler roller 10<SP>1</SP>. The upper unit is adjustably supported by hydraulic rams to vary the spacing between the contact rolls between which the workpieces are fed by upper and lower driven rollers 13<SP>1</SP>. The contact roller 11<SP>1</SP> is journaled in bearings 24 carried by a beam 25 fixed to the frame of the unit 6. The idler roller 10<SP>1</SP> is carried by a yoke 27 which is acted upon by a pneumatic cylinder 28 to tension the belt and is oscillated by a motor 29 to cause the belt to move to and fro axially of the contact roller through a distance equal to about one third of the width of the belt. The axis of the contact roller is disposed at 15 to 30 degrees less than squareness to the path of the work. The belt may be driven at 6000 s.f.p.m. and the workpieces fed at 800 f.p.m. The frequency of the to-and-fro movement of the belt may be between 20 and 30 per minute.

Abstract: 1337367 Carbon fibres STAMICARBON NV 16 Feb 1972 [18 Feb 1971] 7211/72 Heading C1A Tarry material (as defined) containing a finely divided polymer immiscible therewith and in a proportion sufficient to increase the strength of the material on being spun or extruded, is spun or extruded at a temperature above the softening point of the tarry material and the so-formed fibres converted into carbon fibres. Suitable polymers include polymers or copolymers of acrylonitrile and cyclic amides, e.g. lactams, particularly high molecular weight #-caprolactam, and may be used in powdery form in amounts from 5 to 70% by weight based on the tarry material. It is preferred that the melt index (as defined) of the polymer at the extrusion or spinning temperature is lower than that of the tarry material at that temperature. The tarry material may be used as in a powdery form, or it may be formed into a melt into which the powdery polymer may be incorporated.

Abstract: 537,590. Gas motors. WALLACE & TIERNAN CO., Inc. April 22, 1940, No. 7262. Convention date, June 1, 1939. [Class 54] [Also in Groups I and XXVI] In a modified form of the apparatus described in Specification 449,124 for the controlled supply of gas, especially chlorine for treating water, the gas is passed from a chamber 10 where it is confined over water at a constant pressure to a second constant pressure chamber 31, from which it is supplied to an aspirator 32, by a feeding member 40 having one or more pockets 41, which are filled in the gas space and carry the gas down to a position from which it can enter the chamber 31. As shown the feeding member is in the form of a disc 40 with a circular series of apertures 41, the disc being carried by a hub 45 on an inclined shaft 42 driven by a constant speed motor 60 through a speed-varying device 61 provided with a calibrated dial 63. A plate 50 seals the upper ends of the apertures 41, until they are below the space 31 and can discharge the gas thereto. The amount of gas passed is regulated by altering the speed of rotation of the disc 40 or substituting a disc with apertures different in number or size. The chamber 10 is formed by a bell 11 standing in a tray 12 from which water supplied through a pipe 13 overflows through a pipe 15. The gas is supplied to the bell through a valve 21 controlled by a float 22. The gas passes from the chamber 31 through a tube 55 to a chamber 35, the open lower end of which dips into water maintained at a constant level in a tray 36 by means.of an overflow 38.

IPC: F01M5/00
Filed: 1926-03-18
Abstract: 274,535. Dyche, E., and Davies, G. March 18, 1926. Radiators, motor-car and like.- A receptacle 2<a>, Fig. 1 mounted below the crank casing 6 or below an existing oil sump of an internal combustion engine has one or more air passages 5 through it for cooling the oil, which may be circulated from and back to the fly-wheel case 7 through pipes 8, 10. The air inlet 5<a> may extend in the direction of travel of the vehicle and the air passage may be large so as to provide only a narrow channel for the oil. The pipe 8 may connect to the side of the fly-wheel case opposite to that shown. In a modified construction shown in Fig. 4, the oil is circulated by a pump, connected to a pipe 16, through openended pipes 14, 15 in the oil chamber arranged alongside the air passage. The flow of cooling- air may be varied by regulating the size or shape of the air inlet or outlet, and for slow-moving vehicles a fan may be employed.

[Class 59] In a grinding-mill comprising a hollow frusto-conical casing and a substantially frusto-conical member adapted to rotate therein, a portion of the said member being oval in cross-section, the material to be ground is introduced under pressure between the casing and rotatable member. As shown, Fig. 1, a frusto-conical grinding member 4 rotates in a similarly shaped fixed casing 1, part of the member being ground out of true, as shown at 6, Fig. 5, thereby forming, with the casing, a gradually decreasing clearance space from the ,inlet end 3. Material to be ground is pumped from the hopper 11 to the closed end of the casing by pump 9 and after grinding is collected in the annular grooves 8 formed on the member 4 from which it is scraped by a scraper. The casing may be resiliently mounted for self-alignment and may be provided with water cooling means as may the rotatable member 4. This latter member may have, in addition to its rotary motion, an oscillatory movement and it may be adjustable longitudinally relatively to the casing in order to allow a varying flow of ground material to enter the grooves 8. According to the Provisional Specification the oval cross-section of the member 4 may be replaced by a number of tapered flats ground thereon.
